, 2009 We discuss in details the role of Wigner 6j symbol as the basic building block unifying such different fields as state sum models for quantum geometry, topological quantum field theory, statistical lattice models and quantum computing.

Quantum Simulation of Non-Abelian Lattice Gauge Theories [PDF]
, 2013 We use quantum link models to construct a quantum simulator for U(N) and SU(N) lattice gauge theories. These models replace Wilson's classical link variables by quantum link operators, reducing the link Hilbert space to a finite number of dimensions.

Two-particle scattering from finite-volume quantization conditions using the plane wave basis
Journal of High Energy Physics, 2021 We propose an alternative approach to Lüscher’s formula for extracting two-body scattering phase shifts from finite volume spectra with no reliance on the partial wave expansion. We use an effective-field-theory-based Hamiltonian method in the plane wave

Lattice gas models derived from effective field theory
, 2004 We start from a low-energy effective field theory for interacting fermions on the lattice and expand in the hopping parameter to derive the nearest-neighbor interactions for a lattice gas model.

Parton distribution functions from Ioffe time pseudo-distributions
Journal of High Energy Physics, 2019 In this paper, we present a detailed study of the unpolarized nucleon parton distribution function (PDF) employing the approach of parton pseudo-distribution func- tions. We perform a systematic analysis using three lattice ensembles at two volumes, with

The chirally rotated Schrödinger functional: theoretical expectations and perturbative tests
Journal of High Energy Physics, 2016 The chirally rotated Schrödinger functional (χSF) with massless Wilson-type fermions provides an alternative lattice regularization of the Schrödinger functional (SF), with different lattice symmetries and a common continuum limit expected from ...

Algebraic vortex liquid theory of a quantum antiferromagnet on the kagome lattice [PDF]
, 2007 There is growing evidence from both experiment and numerical studies that low half-odd integer quantum spins on a kagome lattice with predominant antiferromagnetic near neighbor interactions do not order magnetically or break lattice symmetries even at ...
